You do not provide a lot of information. Guessing is hard.

 

with lsusb you can see what is your device. please show this.

 

with lsmod you can see what modules are loaded. please show this also.

 

what is in your /etc/modules-load.d/modules.conf ?

 

thanks, gnasch

cat /etc/modules-load.d/modules.conf
 
# /etc/modules: kernel modules to load at boot time.

# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

Well I see a difference to my working config.

 

I do not have 8188eu loaded, just 8192cu. But these are present too:

rtlwifi                45784  0
rtl8192c_common        33420  0
mac80211              358429  2 rtlwifi,rtl8192c_common
8192cu                627893  0

they get loaded automatically when 8192cu is loaded,
 

 

This is my lsusb with the dongle outwardly looking the same as yours. Please verify the USB ID and report back

The 0bda:8176 one seems identical to mine. Please try fresh unaltered armbian image for orangepi one. No need to compile module, as this is already included.

 

The 0bda:8179 one I know nothing about.

 

Why is 8188eu loaded?

a step forward new issues

1. I installed from scratch newest image

2. 8188eu was there already

3. Inserted my wifi adapter and could start wlan0, no error

4. I tried using same package I use on Raspberry python wifi

5. Installed OK

6. Scanned OK

7. Added SSID OK

8. Tried to connect, display filled with some output and machine freezes

9. Restarted. /etc/network/interface is corrupted

10. Python Wifi package is not available any more (removed?)
